    Organizational Commitment to Community Engagement

    ROR is community-supported, community-driven, community-funded open infrastructure. The community-based aspect of ROR sets it apart from similar efforts in this space.

    The wider ROR community includes users and stakeholders from around the world and across many types of institutions and industries, including publishers, libraries, platform providers, university research offices, data repositories, CRIS systems, government agencies, funders, and more. Community members engage with ROR and with fellow community members through its Community Advisory Group, bimonthly community calls, Steering Group, and Curation Advisory Board, as well as through more informal community discussion forms.
